The commented out lines were set like that because I typically reuse some 50 to 75% of code from previous ones. Basically the PAL16R8 has on it a lead that is marked on the datasheet as a Clock. It uses that lead to, ah, cycle the registers that manage the data input to the eight inputs. So the question remains, what expressions from C# can I use to have a GPIO deliver a timed pulse that would do all of that. Normally I include external hardware to produce the cyclic pulse to do so, but, this whole business when completed will find itself being placed on a series of stacked shields.
